Eventually, despite sending others to their deaths in the ring, Cook and Mags ended up as an act along with the Doctor, where Cook turned Mags into a werewolf and set her on the Doctor. He was killed by Mags but returned to life by the Gods of Ragnarok as their pawn to stop an important medallion getting into the Doctor's hands. (TV: The Greatest Show in the Galaxy)

Sophisticated in manner and with an enquiring and intelligent mind, Captain Cook was nonetheless a very ruthless individual who had learnt to survive at all costs. He became a famous explorer, but he did not care much for the people accompanying him, judging them by their usefulness to his own agenda. To survive, he teamed up with the henchmen of the Gods of Ragnarok in the Psychic Circus and tricked others, like Nord and the Whizz Kid, into dying in his stead.

He never showed any remorse or guilt, claiming to follow the rules of the "survival of the fittest".
